Bell Textron 525 Relentless

Twin Rotorcraft

The Bell 525 Relentless represents a landmark in rotorcraft design as the first commercial helicopter certified with full fly-by-wire flight controls, eliminating traditional mechanical linkages in favor of electronic command systems borrowed from fixed-wing jets and military helicopters. Announced in 2012 and achieving FAA type certification in 2024 after an extended development program, the 525 targets the super-medium offshore oil-and-gas transport and corporate VIP markets, competing directly with the Sikorsky S-92 and Airbus H175. Its fly-by-wire architecture enables advanced envelope protection, reduced pilot workload, and smoother handling characteristics that set it apart from mechanically controlled peers. Powered by twin GE CT7-2F1 turboshaft engines, the Relentless offers a maximum cruise speed around 155 knots, a never-exceed speed of 167 knots, and a maximum takeoff weight of 20,500 pounds. The spacious cabin accommodates up to 16 passengers in high-density configuration or can be outfitted for luxury corporate transport, with large windows and a flat floor optimized for offshore crew changes or executive missions. Its 500-nautical-mile range and 20,000-foot service ceiling position it as one of the most capable helicopters in its class.
